HAND FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 322,683. dated July 21,1885.

Application filed June 9. 1885. (No model.)

To all whom it may concern:

Be it known that I, GEORGE L. CHAPIN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Hand Fire-Extinguishers, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which like letters in the several figures indicate like parts of the construction.

This invention relates to afire-extinguisher which is composed of a metal tube that contains the extinguishing-fluid, and from which it is to be ejected or thrown by the hand; and the invention consists in novel means for stopping the mouth of the tube to hold the fluid secure till it is required for use, and opening the tube to liberate it to put out a fire.

The art most resembling this invention is the Ready Fire-Extinguisher, invented by the applicant, and consisting of a tube provided with a stopper, a portion of which is the same kind and form of glass nipple that is employed by me in this improvement; but instead of combining the said nipple with a solid surrounding part, as in my said former invention, I employ a sheet-metal surrounding part to fill the space between the nipple and top of the tube, and a truncated conical part to support the nipple and make a tight connection there'- with; and then to get the proper leverage on the nipple for the breaking off of that portion which projects beyond the tube a sheet-metal ring is secured to the inside of the tube a suitable distance from its top or mouth end, and the inner edge of the ring is turned upward and projects so far up into the nipple as will hold the inner end thereof in a fixed position when the outwardly-projecting end of the nipple is being broken off. The advantages of this construction are, metal is less yieldingthan a wood or other like stopper, and consequently the nipple is broken off with less force, and the business of manufacturing is simplified, inasmuch as the tinner completes the tubes, leaving the chemist no further labor than to fill them before the stoppers are soldered in.

In many parts of the country the metal and glass stopper combined is almost a necessity, by reason of the difficulty in getting suitable dry lumberat all times when required. A further advantage is, the tube can be filled fuller with the liquid than where the stopper is solid from the nipple to the tube, and the exterior of the latter, including that portion of the stopper surrounding the nipple, can have a uniform finish.

Figure I is a sectional elevation of the upper portion of the metal tube, nipple, and stopper of my improved hand fire extinguisher; Fig. II, a plan view of the lower plate to the stopper removed from the other parts; Fig. III, a plan view of the extinguisher complete; Fig. IV, a horizontal section of Fig. I on line m; Fig. V, an elevation of the cone supporting the nipple removed from the other parts.

A represents the top portion of the tube which is to contain the fire-extinguishing fluid, it being in practice of any size desired; but if it has a diameter of about two and one-fourth inches, and is twenty inches long, it will serve a good purpose, nothing being claimed to be new in this regard independent of the other construction shown.-

B represents a frangible nipple, which is hollow and closed at its outer end, the same as in the Ready Fire-Extinguisher.

E represent a sheet-metal truncated cone,

which is open at both ends, and is formed with the same taper as the nipple B, and in which the nipple is inserted as shown. 7 Formed as a part of the cone E or soldered thereto is a metal ring, D, which, combined with the cone E and nipple B, forms a close stopper to the mouth of the tube A. The ring D is united with the tube A by means of solder, the periphery of the ring at b I) being burred down or up, as shown, simply to form an annular groove to receive solder, but the parts may be connected without a burr. The nipple is made tight in the cone E by means of shellac varnish and fine ground red lead or other fluid-resisting cement.

.The means for supporting the inner end of the nipple, so that a light stroke sidewise on the projecting part of the same will break it off, consist of a metal ring, 0, which is soldered to the inside of the tube A, in this case before the nipple and its other connections are set. The margin of the hole through the ring 0 is turned or burred upward, as shown at (I, so

as to project into the nipple so far as to prevent the lower end from having alateral movement. This form of ring Gis employed Where an annular groove, I, is formed in the tube A after the ring is set to support a wire for hanging the tube up.

Where the wire loop for suspending the tube is soldered to the tube, the ring 0 may be substituted by a ring of plate metal soldered to the end of the cone E, the periphery of the ring fitting substantially the inside of the tube A. As there in such case would be no groove I to prevent it from entering the tube, it would perform the same function as the ring 0 in supporting the inner end of the nipple B.

Having thus described my invention, what GEORGE L. CHAPIN.
